The KLUN (Kinematics of the Local UNiverse) sample of 6600 spiral galaxies is used in studying dark matter in different scales: Type dependence of the zero-point of Tully-Fisher relation indicates M/L \approx 9 – 16 in galactic scale. Preliminary results from a study of selection effect influencing double galaxies give a larger value M/L \approx 30 – 50. Study of the Perseus-Pisces supercluster, using Malmquist bias corrected TF distances and Tolman-Bondi solutions indicates M/L \approx 200 – 600 for the large clusters. Application of developed version of Sandage-Tammann-Hardy test of the linearity of Hubble law inside the observed hierarchical (fractal) galaxy distribution up to 200 Mpc suggests that either \Omega_0 is very small (0.01) or major part of the matter is uniformly distributed dark matter.
